Description
APC Smart-UPS SRT SRT5KRMXLT — 5.4kVA / 5.4kW 3U Rackmount Double-Conversion On-Line UPS
The SRT5KRMXLT is a double-conversion on-line UPS in the 5.4kVA class — the highest level of power protection APC offers in this size range. Unlike line-interactive UPS units that bypass utility power when it falls within acceptable bounds, the SRT continuously converts incoming AC to DC and back to AC through its inverter. The connected equipment never sees raw utility power and the transition to battery is instantaneous (zero milliseconds transfer time).
Why Double-Conversion On-Line Matters at This Capacity
For loads in the 5.4kVA range serving rack-scale data center workloads, healthcare diagnostic equipment, financial transaction infrastructure, or government mission systems, the cost premium of an on-line UPS over a line-interactive UPS is justified by what double-conversion eliminates: no transfer events, no voltage waveform distortion passed to equipment, no failed transfers from neutral-shifted or low-frequency utility events. The SRT continuously regenerates clean pure sine wave power.
Key Features
- True Double-Conversion On-Line Topology: Continuous AC-DC-AC inverter operation. Connected equipment is always on inverter power, never raw utility.
- Zero Transfer Time to Battery: Power events of any duration are absorbed without a transfer event reaching connected equipment.
- Extended Runtime Capable: Supports APC SRT external battery packs for runtime extension well beyond internal battery capacity.
- AP9641 Network Management Card 3 Included: Out-of-box SNMP/web/CLI management, environmental monitoring port, EcoStruxure IT integration.
- Wide Input Voltage Window: Accepts a broader input range than line-interactive UPS, reducing battery cycling on marginal utility power.
- Pure Sine Wave Output: Compatible with all modern active power-factor-corrected loads — servers, blade chassis, network equipment, medical-grade devices.

Ideal Applications and Industries
- Mission-Critical Data Centers: Rack-scale on-line protection for tier-aligned data center power architectures where any transfer event is unacceptable.
- Healthcare and Medical Imaging: Type 1 Essential Electrical System equipment, MRI control systems, CT scanners, and patient monitoring infrastructure under NFPA 99.
- Financial Services and Trading Infrastructure: Trading floor workstations, transaction processing servers, ATM controllers, and banking branch infrastructure.
- Government Facilities : Federal IT systems, emergency operations centers, 911 dispatch infrastructure, and continuity-of-operations sites.
- Manufacturing and Industrial Process Controls: SCADA workstations, DCS controllers, robotic cell controllers, and quality lab instrumentation.
- Broadcast, Production, and Media Infrastructure: Master control rooms, production switchers, and post-production rendering systems where audio/video frame drops are unacceptable.
Specifying a Double-Conversion UPS Correctly
On-line UPS selection at this capacity involves more than VA matching: input voltage and circuit availability, output voltage and outlet types, generator coordination, bypass panel requirements, and runtime targets all factor in. Questyme's power specialists have worked with healthcare engineers, data center architects, and government procurement officers to specify SRT deployments that fit both technical requirements and procurement constraints. Speak with a Questyme power expert before finalizing specification.
